Summary: The researchers have successfully developed a covalent organic framework prepared under mild conditions, which induces bifunctional electrocatalytic activities for both the oxygen reduction reaction and oxygen evolution reaction by incorporating Co nanoparticles. Computational simulations show that this material can effectively promote the adsorption and desorption of oxygen intermediates on the active sites during the reactions, making the electrocatalytic process more efficient. Experimental results demonstrate that the zinc-air battery designed using this strategy exhibits a smaller voltage gap and superior cycling stability.

Summary: A high-efficiency and low-cost bifunctional electrocatalyst for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is designed and fabricated using two-dimensional heterostructure of S/N co-doped carbon nanosheets decorated with ultrafine Ni3S2 quantum dots (Ni3S2-QDs/SNC). The Ni3S2-QDs/SNC heterostructure is formed in situ from Ni3S2 QDs without sulfidation. The S/N co-doped carbon carrier enhances electrical conductivity and creates more active sites for ORR and OER. The Ni3S2-QDs/SNC exhibits better performance than Pt/C and RuO2 as a catalyst for ORR and OER, and the assembled Zn-air battery with Ni3S2-QDs/SNC air cathode shows improved power density, energy density, and stability compared to Pt/C-based Zn-air battery. Density functional theory calculations confirm the enhanced capacities of Ni3S2-QDs/SNC for both ORR and OER.

Summary: A strategy of asymmetric interface preconstruction is proposed to fabricate asymmetric air cathodes for high-performance rechargeable zinc-air batteries. The asymmetric interface is preconstructed by introducing immiscible organic-water diphases within the air cathode, at which the electrocatalysts are in situ formed to achieve an asymmetric configuration. The as-fabricated asymmetric air cathodes realize high working rates and long cycling stability.

Summary: This study presents the synthesis of Co, N, and S co-doped hollow carbon nanoboxes (Co-N/S-CNBs) with topological defects. The Co-N/S-CNBs exhibit excellent bifunctional catalytic activity for both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline electrolytes, surpassing commercial catalysts. The formation of topological defects is attributed to the cracking loss of small molecules from polyphenylene sulfide (PPS), acting as active centers to enhance the catalytic performance.

Summary: In recent years, there has been an increasing interest in riding two-wheelers (e.g., bicycles, electric bicycles, electric mopeds, etc.) in urban areas. Mixed-traffic road segments are common locations where two-wheeler flows mix with other vehicles. Due to the lack of lane restrictions, two-wheelers utilize lateral road space more freely and have multilateral interactions with other road users, posing safety issues. This paper presents a simulation framework that addresses the challenges of modeling the multi-interactions of two-wheelers in mixed traffic. The framework includes three intertwined processes: perception, decision-making, and physical execution. Validation results show that the proposed models accurately capture the observed interactions and motions.

Summary: In this work, optical convolution is achieved through a time-wavelength plane stretching approach on a microcomb-driven chip-based photonic processing unit. Optical neural networks (ONN) have greatly benefited from parallel convolution-operation technology, which utilizes the dimension of optical wavelength to enhance complexity and functionality. However, challenges in high-level integration and on-chip operation remain for this advanced architecture. The authors develop a dedicated control and operation protocol, enabling a record high weight precision and demonstrating comparable processing capability to that of a digital computer in proof-of-concept experiments.

Summary: This paper proposes a new method for preparing flexible pressure sensors by combining an imprinting technique with blade-coating of a graphene-silver nanosheet-polymer nanocomposite. The sensor consists of interdigital electrodes, a sensing layer, and a micropillar array structure. The sensitive layer morphology is characterized using scanning electron microscopy (SEM). The test results show that the sensor has an initial resistance of 1.6 ohms, a sensitivity of 0.04 kPa(-1), and a response time of about 286 ms. Furthermore, the sensor exhibits a highly hydrophobic wetting property with a contact angle of 137.2 degrees, indicating its self-cleaning property. Finally, the prepared sensor is demonstrated as a wearable device, showing promising potential in practical applications.

Summary: There is uncertainty about the usefulness of CDK4/6-inhibitor-based therapy for HR+, HER2-, MBC when previous CDK4/6 inhibitor treatment has failed. A biomarker for abemaciclib resistance has not yet been identified. This study reported positive outcomes for an HR+/HER2- MBC patient treated with abemaciclib and exemestane, who had cancer progression after palbociclib and fulvestrant treatment. The potential benefit of PI3K inhibitors after cancer progression needs further investigation using next-generation sequencing.

Summary: In this study, a genome-wide association study was conducted on malic acid (MA) metabolism in tomatoes. Several associated SNP variations were identified, and 15 high-confidence annotated genes were predicted. The transcriptome data of candidate genes were explored, revealing specific expression patterns in fruit pericarp. The study also found that the MA content in tomatoes has been influenced by domestication sweeps and less affected by improvement sweeps in breeding history.

Summary: This paper investigates the common (slack) due-date assignment single-machine scheduling with controllable processing times within a group technology environment. The cost function minimizes scheduling (including the weighted sum of earliness, tardiness, and due-date assignment, where the weights are position-dependent) and resource-allocation costs under linear and convex resource allocation functions. If the size of jobs in each group is identical, the optimal group sequence can be obtained via an assignment problem. Furthermore, the problem is shown to be polynomially solvable in O(P-3) time, where P is the number of jobs.

Summary: The loss-of-function variants in TRIM37 gene cause Mulibrey nanism, an autosomal recessive disorder characterized by severe growth failure and constrictive pericarditis. These patients also experience recurrent respiratory infections and increased mortality rate. The study found that TRIM37 variants are associated with recurrent infection, and Trim37 knockout mice are susceptible to influenza virus infection. The Trim37-Bcl6 axis plays a crucial role in controlling T-FH cell development and high-affinity antibody production, revealing the immunologic mechanism underlying recurrent respiratory infection in Mulibrey nanism.
